Definitions:

Action Potential

A rapid increase and subsequent decrease in voltage across a cellular membrane, allowing neurons and muscle cells to communicate and react to stimuli.

Convergence

The evolutionary process where organisms from different evolutionary backgrounds develop similar traits or features in response to similar environmental challenges or functional needs.

Typical Neuron

A cell of the nervous system, characterized by its ability to receive and transmit electrical signals throughout the body.

EPSPs

Excitatory Postsynaptic Potentials, which are temporary increases in postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell.
